According to some sources, it appears that the Teutonic Order owned land outside the walls of the city of Aachen from the mid-13^th century onwards, but it was not until around 1322 that they established a commandery there, thanks to the donation of a farm and adjoining chapel by a certain Goswin von Keversberg, a member of the city council. The preceptory of Aachen was soon granted land in the "neighbouring" towns and villages of Aldenhoven, Simpelveld, Vaals and Weltz.

One of the distinctive features of this commandery is that until the mid-16^th century, it seems to have been primarily concerned with managing the parish of Sint Aegidius (or Saint Gilles), its commanders being almost exclusively priests. The first knight to become commander of Sint Aegidius was Johann von Cortenbach in 1543.

The first commander, Father Thomas von Aken, quickly undertook work to modernise the farm and chapel that were part of the initial donation. Thus, in 1330, a new chapel appeared on the site of the old one, which he had demolished.

Heavily damaged in a fire in the mid-17^th century, the commandery was rebuilt and enjoyed a period of great development.

At the beginning of the 19^th century, during the Napoleonic period, the Sint Aegidius commandery in Aachen was dismantled. The main building was converted into barracks for the Imperial Gendarmerie and the chapel became stables.

Today, nothing remains of the commandery buildings, except for a few traces in the remains of the medieval walls still visible in the city.

The archives have left us with the names of the first commanders of Sint Aegidius :

• Thomas von Aken (1322 - 1330)
• Christian Sluf (1330 - 1338)
• Godeschalk van Aken (1338 - 1378)
